Repointing Time of Satellite Antenna

07 Jun 2008 (Updated 03 Nov 2009)

A model to compute the repointing time of a satellite antenna on two overlapped visibility circles

File Information
Description	Given the orbital parameters of a satellite equipped with a steerable antenna and the locations of two ground stations whose visibility circles are overlapped (e.g. Matera and Svalbard), the model is able to compute the time spent by the steering mechanism to repoint the dowlink antenna from the first to the second station. Due to the overlapped visibility zones, this repointing time has to be taken into account for the degradation of the overall dowlink performances.
